Oh yes, definitely. The main effect would, I'm sure, be the direction in which the air spills off the edge of the sail. For a flat, rigid sail (a board?) the faster moving air would mainly emerge at right angles to the line of the craft, with equal forces in each lateral direction - no resultant force forward or backward.
But you can't afford to be too 'intuitive' when it comes to aerodynamics.
